Abs pump went out on my 90 sc.....replaced with a good used one and reinstalled master cylinder, after filling with fluid and turning the ignition on, my pump runs constantly......is this normal until I bleed the brake lines?
Yes check all wires connectors are just the way they came off seems to be getting no pressure to the accumulator ball when I take the accumulator ball off no bubbles coming out still trying to figure something out
I am really out of ideas I have removed the assembly twice now and checked everything thoroughly and still no pressure being built pump is working wonderful just no pressure being built
I turn the pump on and cracked open the accumulator ball… I eventually took the ball all be way off and nothing is coming out where the ball threads in no air no fluid I cracked the hard line coming from the master cylinder down to the pump nothing coming out those either checked to make sure that my Coupler was still in and it is located perfectly
I pulled it all back out of the car....gonna clean everything and try again.....very frustrated.....thanks so much for all your help.....I think the key is that the motor is running, but not pumping fluid
I got it......took it all back apart...cleaned entire unit out, then I filled the pump up with fluid as best possible. Installed back in car and turned it on and bam it primed as went to full pressure! Bleed the brakes and all is well. No lights on and pump is building pressure perfectly! Thanks for all ur help
